COMPOUND METAL-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 377,976, dated February 14, 1888. n

Application tiled July 21, 1887. Serial No. 244,866. (No model.)

hereby declare that the following is a full,

y clear, and exact description thereof.l

My invention relates to .metal-working machines; and it consists in a combined vise and punching and shearing machine, all as will 'be fully set forth hereinafter, and pointed out in the claims.

In the drawings, Figurel is a side elevation of my device, partly broken`away to better illustrate the construction. Fig. 2 is a transversesectional view on the line 2,2 of Fig. 1, looking down. Fig. 3 is a like View on the line 3 3 of Fig. l. Fig. tis a like view on the line 4 4 of Fig. l. Fig. 5 is a like view on the line 5 5 of Fig. -1. Fig. 6 is a plan view, and Fig. 7 a side elevation, of the upper part or vise portion.'

A is the stationary standard of my machine, having ange a, whereby it may be suspended from a bench, (when used in a vertical position,) and above this is the head B, containing one jaw of the vise.

C is the swinging standard, having a head, D, containing the other jaw of the vise and pivoted at b between a pair of bearing-strips, E E, which are themselves secured to the stationary standard A, between the lugsd d, by bolts c. meet at the top on the vertical line e, and below the same-each has a V-shaped concave face, ff, making a pipe vise or jaws for round objects, and in order that objects as small as wires may be grasped and held by said vise each of these .heads B and D is centrally cut away, the former to form a V-Shaped convex surface, g, (exactly the opposite of its face f,) while the head D is provided with a central groove, h, to receive a sliding head, F, which has a V-shaped concave serrated face, fi, the said head F being moved forward or back in its groove by the screw G, whose head is secured to the rear end of the head F, and whose shank'proj ects through a screw-th readed opening in the head D and may be provided with a bar, j, or other device for readily turning it.

The heads B D of the vise portion The .base of my machine is formed with two parallel horizontal arms, I andl J, the former extending from the standard A and rigidly united at that end by a piece, H, having projecting ears 7.a 7c, said pieces and earsv being flush with the outer edge vof the standard A, so that the device may be placed horizontally of its greatest length on a bench when more convenient to operate it in this position than in the vertical position shown in Fig. 1.

The swinging standard C projects below the bottom line of the arms I and J, and is bifurcated to receive one end of a link, K, pivoted' at l to said standard, the other end -of said link being pivoted at m to the eccentric head n of thelever L, said head n being similarly bifurcated to receive this end of the link-K, and having a camfsurface, o, above the link K,l adapted to bear thereon, the head being itself pivoted at p between the arms I and J. The standard C is provided with a pin or stop, q, and the Standard A with a detent, M, pivoted thereto at 1" and having a notched face, s, and when the jaws of the vise have been adjusted the desired distance apart, in order to more rmly hold any object between them, vthe detent M is brought up so that one of the notches in its face s shall engage with the pin q, and thereby insure steadiness and security in the relative positions of the standards A and C and the jaws of the vise formed thereon.

- I will next describe the punching device.

The upper part of the standard A, just becured by set-screw w in the stock Q, which in turn is pivoted by'bolt w to the standard C, the rounded ends of said stock tting within a suitable recess formed therein. It is designed to use a series of these punches P corresponding to the diameters of the holes tt t in thev Y ICO block N, which block is moved within its groove so as to bring the corresponding hole t opposite the hole v in the supporting-block O for use in connection with the particular punch to be used at any time. Below the line of the bearing-stri ps E E are located the shearing devices, consisting of the blades R R, se-4 cured within suitable recesses, .e z, in the standards A C by bolts y y.

The operation of my machine will be readily understood by the foregoing description of its construction. p

All of the parts are operated by the lever L, which brings the swinging standard C and its attach men ts against the stationary standard A, so that the metal being worked can be held between thejaws of the' vise or punched or sheared at will by a single movement of the lever L.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isV

1. The combination of a stationary standard and a swinging standard pivoted thereto, the said standards being provided at their upper ends with vise-jaws, with an operatinglever having a cani-head pivoted to the base-frame of the machine and united by a link to the lower end of the said swinging lever, substan-V tially as and for the purpose set forth.

2. The combination of astationary standard, a swinging standard pivoted thereto, an operating-lever having a cam-head pivoted to the base-frame of the machine and linked to the lower part of the swinging standard, and visejaws and punching and shearing devices carried by the said standards and adapted to be operated by a movement of the said lever, substantially as and for the purpose set forth.

3. The combination of a stationary standard and a swinging standardpivoted thereto, each standard having a head with straight and V- shaped concave-faced vise-jaws formed on their opposing inner surfaces, and an operating-lever pivoted to the base-frame of the machine and linked to the swinging standard, a pin or stop projecting from one of the standards, and a detent wlth notched face for engagement with said pin or stop, pivoted to the other standard, substantially as set forth.

4. The combination of stationary standard A, having head B, provided with V-shaped concavefaced vise-jaw f, centrally cut away, so as to leave an interior convex-faced V -shaped surface, g, with swinging standard C, having head D,provided with V-shaped concavefaced vise-jaw f, having central groove, h, sliding block F,and adj usting-screw G, and operatinglever L, substantially as set forth.

5. The combination of stationary standard A, provided with a transverse groove and perforated block N, adjustable therein, and supporting-block O, bolted to said standard below said groove and having an opening through its upper offsetl portion, with the swinging standard C, pivoted to standard A and bearing stock Q and punch P, and the operating-lever L, substantially as set forth.

6. The combination of stationary standard A and swinging standard C, pivoted thereto, with the shearing-blades R R, secured by bolts y y within recesses z z in said standards opposite each other, and the operatinglever L, having a cam-head pivoted to the base-frame of the machine and linked to the swinging standard C, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milton, in the county ofRock and State of Wisconsin, in the Y
